Detectives monitoring the perverts three days ago believe the numbers are low because it’s hot outside.

One expert, Andy Morling, says: “Sometimes this map is covered with hundreds of dots, you’d be surprised how many.”

Each one represents a pervert viewing pictures of children suffering horrific ordeals.

The paedos — usually white males aged 19 to 45 — think they are beyond detection as they log on to various websites and chatrooms. But they are wrong.

Tucked away in the corner of an ordinary looking office, cops of the Child Exploitation and Online Protection Centre constantly monitor their computer map as they try to bring the offenders to justice.

Peter Davies, head of the CEOP, reveals: “We can look at the whole world and see who is online right now sharing child abuse images.

“This programme is on 24 hours a day monitoring these people.

“We can zoom right in on the street they live in. They have no idea we are watching them.”

And he has a warning to the paedophiles: “You have nowhere to hide. We will hunt you down.”

The computer is in the Victim Identification Suite at the centre in Victoria, central London.

Inside, a sign on the wall warns: “There may be disturbing sounds and images in this room.”

Looking at the screen, Mr Davies points at one flashing dot in the capital.

He says: “Judging by where it is I would say that person is accessing child abuse images at work.

“He could be surrounded by colleagues who have no idea.”

A report by the centre revealed the sharing of indecent images of children (IIOC) is on the rise.

And a disturbing recent trend has emerged of IIOCs being made to order.

Mr Davies says: “People can ask for a particular act to be done to a child. The image will be generated and then swapped for others.

“We estimate there are 50,000 to 60,000 people in the UK involved in possessing and swapping IIOCs.”

Images range from Level 1 to the worst Level 5. And the level of abuse in many has become more extreme.

Mr Morling says: “The images are veering towards the top end of the classifications. We are not sure why.”

The age of abused kids is getting younger, with victims including BABIES and TODDLERS.

Mr Davies has been angered by cases in which light jail terms, sometimes of just a few months, were handed to offenders with thousands of child abuse images.

He points out: “Around 55 per cent of people who view IIOCs go on to commit child abuse.

“The people producing these images are abusing children.”

Cops across Europe are working together to tackle the menace.

A recent UK operation involving 40 forces led to the arrest of 104 suspected perverts and 80 kids being rescued.

Mr Davies says: “In one case we were alerted by Danish police that IIOCs they had found were taken in the UK.

“We found the victim within a day. A man was later jailed for ten years for rape and child abuse image offences.

“It’s a result like that which keeps people going — getting an offender locked up, saving a child, that’s a great reward.”
